The coordinate plane below represents a city. Points A through F are schools in the city.
1 answer:
PART A: The equation I used is y<span>≥-1x+4. The line will be graphed going diagonally from the second quadrant to the fourth quadrant and shaded above the line.
PART B: Plug in the coordinates for point C and F into the equation from PART A and solve them to make sure the statements are true. You should end up with 2</span>≥2 for point C and 4<span>≥1 for point F.
PART C: First graph the equation and then shade below the line. Next, identify all the points in the shaded area.
I hope this helps you! I have provided pictures of both equations for reference. The first picture is for PART A and PART B. The second picture is for PART C. Let me know if I'm correct :)</span>

Answer:
<u>640 pounds </u>
Step-by-step explanation:
The rest of the question is the attached figure
So, the total volume = V(cylinder ) + V(cone)
The volume of cylinder = π r² h
The volume of cone = π r² h/3
Both of the cylinder and the cone have the same diameter = 14 inches
So, the radius = 14/2 = 7 inches
The height of the cylinder is 13 inches and the height of the cone is 9 inches.
So, The volume of cylinder = π r² h = π * 7² * 13 = 2,001.2 in³
And The volume of cone = π r² h/3 = π * 7² * 9/3 = 461.8 in³
So, the total volume = 2,001.2 + 461.8 = 2,463 in³
So, the total weight = 0.26 pounds per cubic inch times the total volume
= 0.26 * 2463 = 640.38 pounds
= <u>640 pounds (to the nearest pound)</u>
